SPRING-"G EAR FOR CARRIAGES.

SPECIFICATION forming part of Letters Patent No. 593,831, dated November 16, 1897.

Application filed July 1, 1897- Serial No. 643,109. (No model.)

To all whom it may concern:

Be it knownthat 1, JAMES HAINES CAF- FREY, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Carriages, Wagons, &c., which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists of improvements in carriages, wagons, &c., and comprises the combination of an elliptic or full spring with a spar and bolster for the Winsor parts or featur'es.

It further consists of novel details of construction, all as will be hereinafter fully set forth, and pointed out in the claims.

Figure 1 represents a perspective view of a device embodying my invention. Fig. 2 represents an end elevation of a portion of the device on an enlarged scale. Fig. 3 represents a sectional view on line x 00, Fig. 1, on an enlarged scale. Fig. 4. represents a sectional view on line y 'g, Fig. 1, on an enlarged scale. Fig. 5 representsa sectional view on line 2 a, Fig. 1, on an enlarged scale. Fig. 6 represents a sectional view on line a a, Fig. 1, on an enlarged scale.

Similar letters of reference indicate sponding parts in the figures.

Referringto the drawings, A designates the front axle, which is crank-shaped, curved, or arched, or sprung up, so as to permit the horse to be harnessed close to the carriage, wagon, &c. without risk of striking the same. On said axle'is the bolster B, which is procorrevided with a pivotG, the same being adapted to rest in the socket D, which is attached to the sleeve or portion of the spars or side-bars E by means of bolts F, passing through spurs or lugs G on said socket D. The rear ends of said spars or side-bars E are supported by shackles H, fitting over and around them, and which hang from the bolster J attached to the elliptic spring K, supported on the back axle L, which latter may be of any desired shape. The axles are held in position by the sidebars E and the double perches M, the rear ends of which are attached to the rear axle and near the front ends of the fifth-wheel or circle N and to the front axle A by any suitable sockets orclips, it being noticed that said perches M are bent upwardly, as at P, in order to conform to the height of the front axle. The body is hung between the side-bars or spars E in front by a cross or spar spring Q, which is suitably attached to the said sidebarsE in any convenient manner, and in the rear by supports R, which are attached to the said body and are carried by the'side-bars E, the latter being provided With-sockets S at their inner sides, which are adapted to receive pivots T, which are on the outer ends of said supports R.

U designates the shaft-boxes, which are forged on and made part of metal braces or supports V in such position that pulling or holding back of the horse shall not tend to roll, turn, or twist the axle of said boxes, also bringing the draft midway between the pivotbearing of the front bolster and the center of the spindle of the axis on a level with the line of draft.

One advantage obtained by the use of a construction of this kind is to allow the driver or occupant to shift his position in front of the center of the seat and thus throw the bulk of the load on the front ends of the spars or side-bars, which are carried by the bolster supported on the axle in front, thus avoiding all-forward spring motion and giving the effect of a rigid bolster or Winsor wagon; or

the driver can shift his position so that the bulk of the weight will be back of the center of the seat and thus shall be thrown on the rear ends of the spars or side-bars, which are supported by the shackles above described, attached to the elliptic or full spring. This obtains a soft, easy, and comfortable riding of elliptic or full spring wagon without any tendency of the body to tilt or jump up in front or to pitch to one side, as is usual in fullspring wagons, particularly when crossing gutters,-curbs, holes, or rough places.

The front axle, which is crank-shaped, curved, or arched, or sprung'up, as above described, is stiffened, braced, strengthened, filled out, and finished by the brace or supports T, which extend from the shoulders of the spindles to each end of the axle-bed, thus forming a truss which when fastened to the strength and overcomes all defects and weaknesses of the crankshaped, curved, arched, or sprung-up axle.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A carriage, wagon, &c. having a crankshaped, curved or arched or sprung-up axle, side-bars or spars the forward ends of which are adapted to be supported in any suitable manner upon said axle, and an elliptic spring on which the rear ends of said spars are adapted to be suitably supported.

, 2. A carriage or wagon 850. having a crankshaped, curved, arched or sprung-up front axle, a bolster supported thereon, side-bars or spars supported by said bolster, a second bolster supporting the rear end of said spars and an elliptic spring supporting said lastmentioned bolster.

3. A carriage, wagon, 810. having a front axle, a bolster supported thereon, pivots on each end of said bolster, side-bars or spars having sockets which are adapted to receive said pivots and support the front ends of said spars, a bolster to which the rear end of said spars are adapted to be secured, a spring carrying said last-mentioned bolster,supports for the body, pivots on said supports and sockets 011 said side-bars receiving the latter-named pivots.

4. A carriage, wagon, 850. having a crankshaped, curved, arched or sprung-up axle, a bolster thereon, side-bars or spars which are adapted to be supported by said bolster, and by a second bolster, an elliptic spring mounted on the rear axle and supporting said second bolster, and perches which are secured to said front and rear axles.

5. A carriage, wagon, 850. having a crankshaped, curved, arched or sprung-up axle, an elliptic spring supported upon the rear axle, side-bars or spars which are suitably supported upon said front and rear axle, supports on said side-bars to which the body is secured, and cross or spar springs secured to said sidebars.

6. A carriage, wagon, &c. having a front axle, an elliptic spring supported upon the rear axle, side-bars suitably supported on said front axle and said elliptic spring, a cross or spar spring on said side-bars, sockets on said side-bars and supports having pivots, which are adapted to enter said sockets.

'7. In a carriage,wagon, &c. a crank-shaped, curved, arched or sprung-up axle, shaft-boxes thereon, and braces or supports which are secured to said shaft-boxes and to said axle forming a truss.
